What is the measure of angle Y in this figure

Y=____ degrees

Answer:

Step-by-step explanation:

The 2 factors of x^2 - 9x + 14 are (x - 7) and (x - 2) because -7 + -2 = -9 and -7 x -2 = 14.

The factors of the quadratic expression  x² – 9x +  14 is (x - 7)(x - 2) option (B) (x - 2) is correct.

Any function of the form [tex]\rm f(x) =ax^2+bx+c[/tex] where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic function.

It is given that:

The quadratic expression is:

= x² – 9x +  14

Using factor method:

= x² – 7x - 2x +  14

= x(x - 7) - 2(x - 7)

= (x - 7)(x - 2)

The factors of the quadratic expression  x² – 9x +  14 is (x - 7)(x - 2)

Thus, the factors of the quadratic expression  x² – 9x +  14 is (x - 7)(x - 2) option (B) (x - 2) is correct.

Answer:

x = 6

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are in proportion, that is

[tex]\frac{MO}{PR}[/tex] = [tex]\frac{MN}{PQ}[/tex] ( substitute values )

[tex]\frac{4+x}{5}[/tex] = [tex]\frac{x-2}{2}[/tex] ( cross- multiply )

5(x - 2) = 2(4 + x) ← distribute parenthesis on both sides

5x - 10 = 8 + 2x ( subtract 2x from both sides )

3x - 10 = 8 ( add 10 to both sides )

3x = 18 ( divide both sides by 3 )

x = 6

The systems of equations are known to be complex. We often use systems of equations in real-world scenario such as when calculating or thinking if one will make more money at one job than the other, here we look into variables such as wages, benefits and commissions, etc.

They  are used to calculate the amount of tax that is charge to people. They also help man to measure and understand the real- world situations and happenings.

The field or career that Equations are known to be widely used are the engineering profession. Chemical engineers, civil engineers, electrical engineers, etc. often uses it in construction of building, lighting a place, etc.

The Systems of equations are often applied in the real world by economists and entrepreneurs to known the time of equality of supply and demand.

since our denominator in 6/15 is 15, we could adjust the fraction to make the denominator 100. To do that, we divide 100 by the denominator:

100 ÷ 15 = 6.6666666666667

Once we have that, we can multiple both the numerator and denominator by this multiple:

6 x 6.6666666666667/15 x 6.6666666666667

= 40/100

Now we can see that our fraction is 40/100, which means that 6/15 as a percentage is 40%.

We can also work this out in a simpler way by first converting the fraction 6/15 to a decimal. To do that, we simply divide the numerator by the denominator:

6/15 = 0.4

Once we have the answer to that division, we can multiply the answer by 100 to make it a percentage:

0.4 x 100 = 40%

And there you have it! Two different ways to convert 6/15 to a percentage. Both are pretty straightforward and easy to do, but I personally prefer the convert to decimal method as it takes less steps.

Answer:

40%

Step-by-step explanation:

6/15 = 0.4 = 40%

All these mean the same them, but what we are looking for is a percentage, which is 40%.

[tex]\bold{\huge{\blue{\underline{Solution}}}}[/tex]

Let's start ,

From the figure, we can assume the beam forms as AD, BC, EF , GH and so on.

Therefore,

[tex]\sf{ ABCD , AEFD, AGHD.. so \:on similar\: to \:each \:other }[/tex]

So,

[tex]\sf{ Angle\:BAD = Angle\:EBC = Angle\:GEF}[/tex]

Or,

[tex]\sf{ Angle\: ADC = Angle\:BCF = Angle\: EFH }[/tex]

Now, By using similarity theorem we can determine their sizes, braces and angles that is,

[tex]\sf{\red{ AD/BC = AB/AE = CD/CF = BC/EF}}[/tex]

[tex]\bold{\huge{\blue{\underline{Answers :- }}}}[/tex]

Answer 1 :-

For answering the above questions we use knowledge and practices regarding the questions we can do the activity by making figures of unknown sides by assuming it in the form of x, y.so that we can find the known values.

Answer 2 :-

The best way of solving the above questions is that it is already given in the question that the beam is symmetrical so, here we can use similarity theorem.

Answer 3 :-

It necessary to learn about trapezoid and it's properties because if we don't know the properties and what is trapezoid then we will not be able to answer the given question.

Some properties of trapezoid

Answer 4 :-

Well, The answer is very easy that if we don't know anything regarding the trapezoid then we will not be able to any question based on it and if we have incomplete knowledge about it then we will able to solve it but we always got incorrect answers most probably.

Answer:

The common ratio is -2

Next three terms are 18, -36, and 72

Step-by-step explanation:

The common ratio is -2 since each consecutive term is being multiplied by -2

The next three terms are -9(-2) = 18, 18(-2) = -36, and -36(-2) = 72

Answer:

A -0.5

B 4.5, -2.25, 1.125

Step-by-step explanation:

A: 72× -0.5= -36

-36× -0.5= 18

18× -0.5= -9

B multiple everything by -0.5

From the series, it can be deduced that the sum of the first two terms will be 18.

From the information given, it was stated that the transport charge starts with a minimum charge of R8 and thereafter it was increased by R2 for each kilometre.

The series is also given as S. = 8 + 10 + 12 + 14 +... Therefore, the sum of the first two terms will be:

= 8 + 10

= 18

Expressing T2 in terms of S, and S2 will be T2 = S + S2.

Equation: y = 2x + 25

Step-by-step explanation:

Here x determines the number of year. For the first year,we will see ( 2 * 1 ) = $2 increase. In the second year, ( 2 * 2 ) =$4 increase and like this goes on, whereas the $25 being constant. "y" determines the total cost for each year.

Answer:

True, it is a solution

Step-by-step explanation:

First, let’s distribute 1/3 to x and 4

When we do this, we get:

1/3x+4/3=20

Now, we can solve the equation!

Subtract 4/3 from each side of the equation to isolate the x

We now have 1/3x=18 2/3

Now we divide 1/3 on each side to isolate the x (this is the same as multiplying by 3/1 on each side)

This gets us to x=56
